Not necessarily. the blue/white off of your alpine is a low current (.1 or .3 amp) 12 volt turn on lead that is made as a turn on switch for an amp. All amplifiers in the system will need a 12 volt signal that let’s them know when to turn on. A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire (or a burned out circuit). So, it was my splicing job that was at fault. IIRC, either Sony or JVC (can't remember which) 2 separate blue wires.

Even if either had drawn 10 amps, it might draw 10 amps for a fraction of a second and then the fuse on the deck would blow. No problems. I didn't try piggy backing the wire from one amp and then from that amp to the other amp. Has worked dozens of time for me. i was just going to splice a wire and use that, since i dont have a designated wire for turn on lead. So the amplifier doesn't stay on 24 hours a day you need a way to turn it on and off remotely. I am not sure why the power supply would be insufficient, unless the splicing reduces the voltage that much. Do you just connect the wires to the same remote screw on the amp when you do this? Now, I am installing a second amp. Although that could be the problem, you wouldn't know because you didn't test each wire end one at a time to the same amp while the wires were still connected. I need a remote signal to turn the amp on when the ignition goes on... FYI - don't use the lead fromt he HU to the amp/changer, as you will pull too much power than the HU can handle and damage the HU....just run a new lead … The turn-on lead from your HU (head unit) will power two amps, no problem. For a better experience, please enable JavaScript in your browser before proceeding. the remote wire purpose is to signal to the amp to turn on or off , via voltage signal. You need to be more detailed. So I put a toggle switch up front, ran one wire to power, and the other wire to where the remote wire is suppose to be anyway. The remote turn-on wire usually comes from the radio, in which case your amplifier won't turn on if the radio isn't on. It doesn't need to be as thick as the power and ground wires (18 gauge should be fine). A Bosch type 30 amp SPDT (single pole double throw) relay is what you need. A forum community dedicated to all mobile audio enthusiasts. While in the ON position, there should be 12+ volts at the remote turn on wire. The days when amp remotes took a lot of current are loong gone. If the remote turn-on wire doesn't have power, your amp won't turn on. Neither amp turned on when power was applied. The remote wire acts essentially like your finger flicking a switch, where your finger is battery power, and the switch is a mechanism inside the amplifier. Using a clarion cz702 to an alpine mrx f65 and alpine mrx m110. I went back and checked it and the relay was pretty hot to the touch...given it was 98 stinkin degrees out but still...does that mean anything? This time, it turned on, so my attempt failed at some point. Watch as we explore the functionality of an amplifier remote turn-on wire. Be sure the positive lead is touching the wire strands inside the jacket of the remote turn on wire. This is because a head unit turn on … Head Unit Has No Remote Wire .

Then turn the ignition to the ON position and test the same way again. so this will work. That's about as clear as I can explain it, hopefully that helps. i just use a barrier strip as a "distrubution block" and ive used relays. Or you didn't check continuity with a meter. There should be a fuse (equal or greater than the combined rating of fuses on the amps) no farther than 18 inches from the + battery terminal.

What brand of stereo do you have? if you supply it with any 12v+ the amp should work. all the remote is, is a 12V current going from the head unit to the amp telling the amp that the HU is on. If you experiencing problems aside from this you may consider a grounding problem. I had run a single remote turn on wire from the head unit to the amplifier and all was well. An Amplifier on the stock radio.. I am running two different amplifiers in my car. well, i have a stock deck for right now and need to know something, with all the cables leading into the back of my deck, will any of the blue wires work for attaching my remote turn on lead?

And yes, just tap in and you run it to the amp's remote turn on. the relay is only used for the small remote turn on wire. you can pick up a relay at your local Radio Shack or on partsexpress. 1) Bad turn on lead coming out of your HU 2) Amp needs more current than normal to turn on (less likely) 3) Turn on wire has a kink or bad connection somewhere along the run Most remote turn on wires can provide at least 150mA of current for turn on purposes, enough to turn on at least 2 or 3 amps as each amp takes only a few tens of mA to turn on. Some draw minimal current. Others draw a little more. I ran one end to one amp and the other end to the other amp. I never thought about this type of potential problem until I needed to wire up three amps. I need to run turn on leads to both amps. What if I'm just running 2 amps, 1 for front and rear and the other for sub? It is showing less than 1 volt. So therefore I need to find a lead to tap into that switches on when the ignition is turned on. Anymore than that, you will need a relay. personally i dont think that was the issue. the remote wire is for powering on the amp. :woot: that means your system won't sound good. One wire is for the power antenna, and the other is the amp turn-on lead.
